An electronic circuit, preferable as a sensor node, has a highly sensitive radio function and is capable of performing a low-power-consumption operation. The electronic device has a board; a connector for connecting a sensor; a first signal processor circuit receiving an input of sensor data from the sensor through the connector and forming transmission data; and a second signal processor circuit converting a transmission signal from the first signal processor circuit into a high-frequency signal. The connector and the first signal processor circuit are mounted on a first surface of the board, and the second signal processor circuit is mounted on a second surface of the board.
